The studies of investment strategy as one of the methods of economic efficacy assessment of high-tech medical care (coronary artery bypass surgery, CABG), when medical care is considered to be an investment project (capital investment — is a high-tech medical care at the cost of R — into patient quality of life improvement) made possible future treatment cost reduction. The research has shown, that CABG is not only high clinical, but also cost effective economic medical intervention. Parameters of investment project efficacy were used to assess medical care cost-effectiveness. The result correlates with medical care value and patient life expectancy.
